tahoe Posted October 23, 2009 Posted October 23, 2009 I've seen the topics discussing the products available but i am wondering if anyone has tried other interface items. I want to convert 0-5v analog input to x10 or insteon and feed it to the isy99. Are there any single analog input devices? I don't need any outputs.
brad77 Posted October 23, 2009 Posted October 23, 2009 I believe that the I/O Linc can do just that. It's got a sense terminal for detecting up to 5 volts. I don't know what the minimum is. It's also got a 3.5mm jack that connects directly to the 5V, ground and sense terminals. If you can't wire it directly, you can hook up a variety of sensors or switches up to it. Smarthome has put together a number of kits that can provide you with examples. The sense terminal can only take a maximum of 5 volts, but a low voltage probe (SH #8015) can be used to detect voltages from 3 to 24 volts. It does have an output, but it doesn't have to be used. The ISY can pay attention to the input and fire off programs in response.
tahoe Posted October 23, 2009 Author Posted October 23, 2009 Thanks but I didn't see any I/O linc devices that read analog inputs. Do you know the i/o linc part number?
brians Posted October 23, 2009 Posted October 23, 2009 The I/OLinc only has a dry input. The 5V has nothing to do with the input. I can trigger the sensor on mine by just shorting the GND and Sense and ISY reports it either On or Off. The 5V purpose appears to be a convenient source for running 5V through the relay circuits for controlling power to devices, if it requires 5V. My application requires 12V so I use an external power supply plugged into the I/OLinc. I am told the EZIO 2x4 should work. I have one on order and will followup when I get.
brad77 Posted October 23, 2009 Posted October 23, 2009 Ah, thanks Brian. It looks like you'd need a low voltage kit to step up from the dry contact sensor in the I/O Linc (SH #24950A4). That is good up to 24 volts. As it is, I'm using an I/O Linc with a magnetic garage door contact switch and it's working great so far. I'm curious about your experience with the EZIO. From what I've read so far, compatibility with the ISY has been spotty. I'm looking forward to hearing about what you think.
brians Posted October 23, 2009 Posted October 23, 2009 Brad, you can also order that part separately from SH #8015 if you already have and I/O Linc. Back to the EZIO... I want to read outside temperature and indoor humidity to control my Humidifier automatically. I currently have a small wall control connected to outside sensor that does this and works well... but, being a geek, I must try to get the ISY to do it SH # 1523 is a cheap temp sensor that gives an output of 0-5V. If EZIO 4x2 works with ISY to read analog, then it should send a value between 0-1023 and this can be used for logic in programs. I think one may have to run the setup from SimpleHomeNet to put inputs in analog mode. To get humidity, I notice SH doesn't have anything like the temp sensor, but since I'm ordering a bunch of stuff from there I found this... SH # 30413A for Venstar. This looks like they use a standard Humidity sensor that I have seen when doing some research online... it should have Vcc, Gnd and Signal. Although it is designed/sold to plug into a Venstar thermostat, I believe it would work standalone but one would have to calibrate the readings to actual humidity.
brad77 Posted October 23, 2009 Posted October 23, 2009 Yeah. I mentioned that same part number for the standalone probe earlier in the thread. My interest is piqued! Please let us know if you get that to work. I've got a separate I/O Linc experiment that I'm doing related to an RFID proximity sensor. I can certainly appreciate your inclinations to geek out.
